Match the function below with the correct part of the joint a) Tough non elastic, fibrous connective tissue joining bone to bone. They restrict the amount of movement that can occur at a joint and provide stability Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) b) Fills the joint capsule; it nourishes and lubricates the articulating surfaces and protects the joint by reducing friction. Becomes less viscous (thick and sticky) with exercise. Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) c) Fibrous tissue encasing the joint, forming a capsule. It adds stability to the joint and prevents unwanted material from entering the joint. Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) d) Covers articular surface of bones and protects the bones tissue by smoothing and facilitating gliding movements between the bone ends. It also helps to reduce friction between the bones. Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) e) Fill the gaps in and around the joints helping to protect the bones from wear and tear. Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) f) Acts as a lining to the inside of the joint capsule and secretes synovial fluid. Choose... Hyaline cartilage Joint / articular capsule Synovial membrane Synovial fluid Ligaments Pads of fat Articular discs (menisci) g) Lie between the articular surfaces and are attached to the capsule at the outer edge. Their function is to absorb shock, protect the bones surfaces and maintain joint stability Choose...
